PROBLEM TO BE SOLVED: To obtain a rotary compressor which prevents that a closed chamber is brought into a vacuum state, and the drive power of the rotary compressor is increased, does not cause an increase of the wear of a vane groove, avoids a behavior of a vane from being instable, and does not need a special processing tool for processing a cylinder.SOLUTION: In a rotary compressor, a discharge hole communicating with a compression chamber is formed at an anti-suction hole side in the vicinity of a vane groove 128T of an end plate, and a penetration hole 140A which makes a closed chamber 132T which is formed while a contact point of an annular piston 125T and a cylinder inner wall in an operation chamber of one cylinder 121T moves to a vane-side end 135Tt of a suction hole 135T from the vane groove 128T, and a suction chamber of the other cylinder communicate with each other is formed at the suction hole 135T side in the vicinity of the vane groove 128T of an intermediate partitioning plate. |
